Abstract

The present invention relates to methods and systems for creating a sound effect out of a continuous movement, in particular by means of detecting a continuous movement through a force sensor in a device. A method is shown for creating a sound effect out of a continuous movement. The method comprises a step of providing a first device, where-by the device is adapted at detecting continuous movement and a no-movement state. The method further comprises the step of defining at least one first parameter of movement, in particular a first axis of movement of said continuous movement. A further step comprises the assigning at least one first midi-channel to the first axis of movement. A base-line value is defined for the no-movement state, and along that first axis of movement a range of values is relative to said base-line value is defined. This range of values is relative to said base-line value is reflective of a continuous movement along that first axis of movement. A sound effect is then output relative to the detected continuous movement. One aspect or additional embodiment of the present invention comprises the step of defining at least one first parameter of movement, whereby said first parameter of movement is an angular range in one axis X, Y, Z of an orientation in space of the first device ( 99.1 ) adapted at detecting continuous movement (A. 1 ) and a no-movement state.
